Title: Discharging apparatus for settled sediment of reservoir pond
Inventor: OGAWA TADAO
IPC: B01D21/24
Filed: 1979-07-20
Abstract: PURPOSE: To facilitate the discharging of the sediment settled on the bottom of the reservoir pond by providing a number of soil intake pipe along the axis of a sediment discharging pipe arranged on the bottom of the reservoir pond and an upward rise pipe at the upstream end.  
     CONSTITUTION: A gate 6 is normally closed. The sediment settled in the reservoir pond 2 accumulates on a cover 12 at the upper end of respective soil intake tube 11. When the sediment settled exceeds the fixed weight, the cover 12 wich is charged to close around an axis with a spring, is released to open and allow the soil to fall into the sediment discharging pipe 3 from the intake pipe. Thus, the soil is taken into the sediment discharging pipe 3. As soon as the gate 6 is opened at a proper timing, water flowing into the sediment discharging pipe 3 from the rise pipe 7 and the respective soil intake pipe 11 flows to a soil collecting pipe 5 with the soil and released downward from the weir 1. Here, if a spiral blade 8 is provided in the rise pipe 7 to cause a turning flow in the sediment discharging pipe 3, the soil can be discharged more effectively.

Abstract: PURPOSE:To form a plated film of a uniform thickness on only the front side of a steel sheet when the sheet is electroplated as the cathode, by detecting both edges of the sheet, dividing the anode confronting the sheet into plural anodes and controlling the amt. of electric current for each of the divided anodes. CONSTITUTION:When electric current is supplied to a plating soln. between a steel sheet 4 as the cathode and the anode 2 to electroplate the front side of the sheet 4, both edges of the sheet 4 are detected with detection terminals 8a, 8b the anode 2 is divided into plural anodes 2A-2I in the lateral direction of the sheet 4 and the anodes 2A-2I are connected to the positive electrodes of rectifiers 5A-5I, respectively. The terminals 8a, 8b are connected to a controller 10 for controlling electric current for plating with an edge detector 9 in-between and total electric current for plating is calculated with the controller 10 from the width of the sheet 4, the amt. of plating, the current efficiency of the cathode and the line speed of the sheet 4. Optimum electric current for each of the divided anodes 2A-2I is then calculated, the value is instructed to each of the rectifiers 5A-5I and the electric current is supplied to each of the anodes 2A-2I. In case of one side plating, a uniform plated film is formed on only the front side of the sheet 4 with no overplating on both edges.
